Air Chicago Style
Littlejohn Inc. provides a rugged lineup of Chicago‑style (Air King) pneumatic fittings, tailor‑made for chemical tank trailer systems. These universal, genderless couplings are designed for quick quarter‑turn connections, allowing seamless link‑up of airline hoses without the concern of male/female orientation. Ideal for chemical hauling applications, these fittings help maintain constant air supply with minimal delay or leak potential during loading and unloading operations.
We carry top-quality Chicago‑style fittings from trusted manufacturers like Dixon and Pelican, both recognized for their robust materials and chemical-resistant finishes. Dixon’s Air King iron couplings are built to withstand the pressures typical in trailer pneumatic systems and include safety clips for secure operation. Pelican’s stainless‑steel male‑thread Chicago fittings offer durable construction and excellent corrosion resistance, perfectly suited for chemical transport environments.
At Littlejohn Inc., we understand how critical reliable pneumatic connections are in chemical trailer systems. That's why we prioritize fast shipping from multiple national warehouses and back every sale with knowledgeable support. Our experienced team can guide you in selecting the right Chicago‑style fittings to maintain safety, reduce downtime, and keep your chemical operations running smoothly.
